• Windows Forms Radiobutton focus oddity

  Looking for some insight... I have a large-ish VB.NET form with a bunch of controls on it (nothing too weird so far). On this form is a couple of radiobuttons, and occasionally when the form is opened, the first radiobutton gets focus (despite them being somewhere down the tab order).

Any clues as to why this would be Thanks, Dave Yes, no worries there, I can shift-tab back to the earlier controls with no problems when this happens. ...Show All

• .NET Development Removing a Relationship in a Microsoft Access Database

How can I remove a relationship between two tables from within my C# program You first need to determine where the relationship is in your code and what it's called. Then you can delete it like this: DataSet1 ds = new DataSet1 (); ds.Relations.RemoveAt(0); ... or ... ds.Relations.Remove( this .myDataRelation); I'm assuming you had the designer create a DataSet for you with all of the related tables, constraints, relationships and so forth Of so, finding the relation is easy: open up the DataSet in the IDE and fi ...Show All

• Visual Basic Extract typed info letter by letter

  What I'm trying to do is have a text box for a user to enter a name into, then extract each letter from that box in order, turn letters into numbers, then screw with that to come up with an apparently random number for later verification (see if the name matches the number).
